Stainless 440C is a high-carbon martensitic stainless steel. As a martensitic stainless steel, 440C is magnetic and can be hardened by heat treatment. The high carbon content in 440C provides high hardness and strength. Despite this carbon content, the chromium content is sufficient to retain its stainless characteristics. 440C STAINLESS In Stock BAR Castle Metals SiteStainless Steel 440C in bar SPECIFICATIONS:GRADE STAINLESS STEEL 440C, AISI 440C, UNS S44004 Castle Metals provides Stainless 440C in bars throughout our distribution network, which spans the United States, Mexico, Canada, France, U.K, Singapore, and Shanghai.
